Title: Improvements in devices for stacking webs in folded layers
IPC: B65H45/101
Filed: 1963-01-14
Abstract: 964, 854. Layering fabric. BENTELERINTERTEX ORGANISATIONS A.G. Jan. 14, 1963 [Jan. 12, 1962], No. 1632/63. Heading D1S. A depositor for stacking a web such as fabric in folded layers comprises a uniformly oscillatory laying roller above the stack to be laid, preceded in the direction of web feed by a compensating roller having an amplitude of oscillation in the rates ¢: 1 to that of the laying roller, the compensating roller being adapted to move in the same direction, as viewed in the direction of web feed, as the laying roller and the web being supplied to the laying roller substantially parallel to its plane of oscillation. In the arrangement shown laying roller 3 is linearly oscillated through a distance '1' above the table 1 in the direction indicated by arrow E so as to lay the 2<SP>1</SP> in a stack 2. Preceding the laying roller 3 there is a compensating roller 4 which is caused to move in the same sense as the laying roller 3 but with half the amplitude i.e. ¢ 1 of roller 3. A stationary, uniformly driven supply roller 5 feeds the web 2<SP>1</SP> uniformly to the depositing apparatus. In operation starting from A the roller 3 moves to B and deposits a length '1' of web. The roller 4 simultaneously moves from C to D and a length '1' of web 2<SP>1</SP> is fed by supply roller 5 thus a length 2 1 of fabric passes the point F one length '1' being taken up by the movement of roller 3. When laying roller 3 returns from B to A roller 4 simultaneously moves from D to C and a length '1' is fed by roller 5. This length however is taken up by the movement of roller 4 so that no fabric passes point F the roller 3 merely depositing the previously extending layer on to the stack 2. Other embodiments show the invention applied the oscillating lever type of layering device.

Title: Improvements in and relating to the sealing of electric conductors into metal tubes
IPC: H01J9/32
Filed: 1937-01-22
Abstract: 489,287. Sealing metal to vitreous material by heat ; thermionic valves. ARCTURUS RADIO TUBE CO. Jan. 22, 1937, No. 1945. Convention date, Jan. 24, 1936. [Class 36] [Also in Group XL] In making sealed metal tubes comprising or forming parts of electrical devices such as vacuum tubes a central aperture in a metal disc is closed by a mass of vitreous material through which the leading-in conductors of the device may be sealed, the metal ring being subsequently welded to the open end of the metal tube or vessel which is closed at the other end. In the example a vitreous mass 11, Fig. 2, with leading- in conductors 14 sealed therein in the manner described in Specification 486,872, is sealed within the central aperture of a metal ring 18 which is formed with a flange 115 around the aperture to facilitate sealing, the operation being carried out by mounting the parts in a head of a rotary turret machine which carries them through the flames of a series of burners which soften the glass before a presser member becomes operative to press the metal and glass into intimate contact. As shown in Figs. 2 and 7, the metal ring 18, is provided, in addition to the flange, 115, with a flattened disc-like portion 75 formed with an annular ridge 76 adapted to provide a welding area between the ring 18 and metal tube 17, and the outer periphery of the ring is provided with a downwardly extending flange 130 formed with tongues 106 which secure the tube and stem to an insulating base 105 by engaging within depressions in the latter. In a modification the ring 18, Fig. 5, is provided with an inner annular groove 77 which opens downwardly and forms the inner periphery of the ring, thus increasing the path of heat flow between the welding ridge 76 and the sealing area in contact with the vitreous material and preventing softening of the latter during the metal welding operation. In a further modification the central aperture in the metal disc is bounded by a plain flange at right-angles to the surface of the disc.

Title: Magnetic data storage arrangements
IPC: G11C11/06
Filed: 1972-01-14
Abstract: 1376995 Magnetic storage arrangements ELLIOTT BROS (LONDON) Ltd 12 Jan 1973 [14 Jan 1972] 1968/72 Heading H3B Information is written by coincident current selection into a column of a matrix of magnetic storage cores 1-9 by pulsing selected row lines 13A-13C in turn while the column write current in a selected line 10A-10C is continuously maintained. The row and column currents are derived from positive sources 15, 21, 29 and are magnitude limited by resistors 14, 22, 30. Row selection for writing is effected by a write control circuit 32 wich controls row drive circuits 17A- 17C, while for writing or read out a column line is selectively energized with a current of appropriate direction and magnitude by a column drive circuit 11, 12 controlled by a column address decoder 20. Capacitors 16, 23, 31 shunting the resistors reduce the rise time of the pulses, and capacitors 39, 40, 41 store sufficient energy to permit a read or write operation to be completed in the event of supply failure. Word read out is obtained on lines 18A-18C and operates bi-stable electronic latching circuits 25A-25C through threshold networks 19A- 19C and sense amplifiers 24A-24C. The latching circuits content may be read via a gate circuit 27 on a main data highway 26A-26C. Alternatively the latching circuits may be set from the main highway through a gate circuit 28 and their content applied to the write control circuit for entering the new information into the matrix. Operation of the write control circuit for sequential energization of the matrix row lines is controlled by a clock, a start write control and an end write indicator being also provided. In the arrangement shown a single supply 15 and resistor 14 is common to all the selected row lines, but in a modification, Fig. 2 (not shown) operational speed is increased by the use of two resistors respectively connected to alternate row lines.
